MET-Rx Big 100 Protein Bar

MET-Rx Big 100 protein bars are a staple in the sports nutrition industry, known for their high protein content and meal replacement qualities. The brand was founded in 1991 by Dr. Scott Connelly, an anesthesiologist who originally developed the formula to help critically ill patients maintain muscle mass. It quickly evolved into a leading brand for bodybuilders and athletes.

Historically, the brand has changed hands several times. It was sold to Rexall Sundown in 2000, which later became part of NBTY (The Bountiful Company). In 2021, when Nestlé Health Science acquired the core brands of The Bountiful Company, MET-Rx was excluded from that deal. Consequently, it became part of a new entity named 1440 Foods, which was formed through a partnership between private equity firm 4x4 Capital and the remaining assets of The Bountiful Company. As of 2026, MET-Rx continues to operate under 1440 Foods, maintaining its reputation for power-packed nutrition. The products are primarily manufactured in the United States, catering to a global market of fitness enthusiasts.
